Secrets of the Dead Sea
Dead Sea – the lowest elevation on the earth's surface
topography, a nadir is a point on a surface that is lower in
elevation than all points immediately adjacent to it.
Mathematically, a nadir is a local minimum of elevation. A nadir
may be the lowest point of a dry basin or depression, or the
deepest point of a body of water or ice. The nadir of a body of
water is often called a "deep", as in the Challenger
Deep, the nadir of the Earth's oceans.
